Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds write (CVE-ID: CVE-2026-0297)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 9 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to out-of-bounds write in the UDP tunnel handshake processing in the GlobalProtect App when handling a UDP tunnel handshake. A remote attacker on the local network can act as a man-in-the-middle or a rogue gateway to execute arbitrary code with highest privileges on the system (e.g. under SYSTEM or root).

No special configuration is required to be affected by this issue.
